Arnott Warns $10 Billion-Plus IPOs Could Drag Equities for Years
1 articles · Updated · Bloomberg · Jun 5
Summary
Rob Arnott said potential listings by SpaceX, Anthropic and OpenAI could siphon tens of billions of dollars from existing stocks, creating a years-long drag on the broader equity market.
S&P Dow Jones Indices' decision not to grant fast-track entry to such large new stocks may slow the impact, but Arnott said the pressure would still build as their index weights rise over time.
Arnott, founder of Research Affiliates, argued the market effect was always likely to emerge gradually rather than in a single shock because capital would be redirected in stages.
The warning points to a broader risk from blockbuster IPOs: even highly anticipated debuts can weigh on incumbent shares when investors must fund new positions at massive scale.
